Abstract
An organic thin film transistor containing a compound represented by the formula (1) in a semiconductor active layer has a high carrier mobility and a small fluctuation of the threshold voltage after repeated driving. R1 to R12 represent a hydrogen atom or a substituent, provided that at least one of R1 to R12 represents a substituent represented by the formula (W), or all of R1 to R12 represent a hydrogen atom. * represents a position bonded to the naphthobisbenzofuran skeleton. L represents a single bond, a divalent linking group, an oligoethyleneoxy group having a repeating number of an ethyleneoxy unit of 2 or more, or an oligosiloxane group having 2 or more silicon atoms.
